2 Section : Configuration Connect power supply to SIP and power up The default connection for the Sanyo AMY is via Serial Port # on the SIP Connect to laptop/pc via Ethernet port for configuration Fixed IP address is To configure the Sanyo serial port: - Select the Baudrate - default Select Port No and click SEND & REBOOT to save changes To configure the Modbus serial port: - Select the Baudrate - default Select the Port type - default RS - Select Port No and click SEND & REBOOT to save changes NB: Sanyo Software for the AMY uses a Baudrate of The AMY may be set to 900 (default), therefore either the the AMY or the SIP has to be changed. The rest of the serial port settings are 8-databits, no parity, one stop bit.

In each AMY there are adaptors, per link. Each link is a Modbus slave containing up to 6 units.
